CL, H. FENNELL WHEEL CHOCK Filed Dec. 26, 1925 Patented Feb. 15, 1927.

UNITED` STATES PATENT OFFICE- I CHARLES H. FENNELL, OF DETROIT, MICHIGAN.

Application filed December This invention relates to wheel checks and has special reference to that class of wooden blocks which are placed against the wheels of an automoble to prevent accidental shitting of the automobile on a floor or other support, particularly during shipment of the automobile from the manufacturer to the distributor or user. It is the present practice to use tire engaging blocks having end extensions which are nailed, spiked or otherwise secured to a ear floor but such securing means is often times inetfective and the blocks laterally shift and become loose.

My invention aims to provide additional securing means for anchoring wheel chocks in place so that the chocks cannot become accidentally displaeed. The additional securing -means add very little expense to the chocks and can be easily and quickly installed.

My invention will be hereinaiter specifically described and then claimed, and reference will now be had to the drawing, where- 1n-- Figure 1 is a side elevation of a wheel retained'in place by a set of checks secured to a floor;

' Fig. 2 is a perspective View of one of the' checks or blocks;

Fig. 3 is a side elevation of a block illustrating another form ot securing means;

Fig. 4 is a similar view showing a simple 'form of securing means, and

Fig. 5 is an end View oit' the structure showh in Fig. 3.

Reterence will first be had to Figs. 1 and 2, showing an automobile wheel 1 resting on a car tloo` or other support 2 and to retain the wheel in place, against accidental Shifting on the floor 2, a set of blocks 3 are enployed, said blocks having concave o'' grooved tire engaging faces 4 with the outer ends of the blocks provided with extensions 5 adapted to be secured to the floor 2 hy nails 63 spikes oother tastening means. Thesehlocks are ordinarily made ot wood and my invention resides in providing additional retaining or securing means for the blocks.

Each block is provided with a transverse clove-tailed groove 7 in its lower face and. mounted in the groove is a transversely dispsed bar 8 having; its ends protruding from the side's of the block to form later'i ***ide h'eeetiohs Ftted the e aide WHEEL CHOCK.

26, 1925. Serial No. 77,771.

tions are the dove-tailed portions 10 of straps 11 and said straps eXtend in a general direction of the block 3 and are adapted to be secured to the floor 2 by nails 12, spikes or other fastening means. Similar fastening means 13 may extend through the straps and the ends of the bar. i

Instead of using a dove-tailed bar I may use a bar 14 substantially rectangular in cross section with said bar fitting in a correspondingly shaped groove in the block 3. Straps 15 may be mounted over the ends of the bar 14 and secured to the block 2 by the same fastening means 12 and 13 heretofore mentioned.

In some instances the straps ll and 15 may be dispensed with and the ends of the bars 8 or 14 nailed or otherwise secured to the floor 2, as shown in Fig. 4. After the blocks 3 have been properly positioned relative to the wheel 1 and secured in place on the floor 2, the bars 8 or 14 may be placed in the blocks 3 and secured to the floor, or if straps are used on the ends of the bar said straps can be easily placed in position and secured to the floor.

My additional tastening means aiords positive and reliahle securing` means 'tor the wheel blocks or chocks, and it is to he understood that the Construction is sisceptible to such changes as are permissihle by the appended clains.

lVhat I claim is:-

1. In a wheel chock adapted to he anchored on a floor adjacent a wheel, a detachahle bar in the lower face of said chock and having' its ends protrudingfrom said chock and means engaging the bar ends` adapted to ane-hor said bar to the fleoix 2. A wheel chock comprising a wheel engaging block having side lateral projeetions adapted for anchoring` the block on a surtta.ce said lateral projections being connected and adapted for movement transversely of said block.

3. A wheel. chock comprisin' a wheel engaging block having its lower face gro'oved a bar mounted in the block grove and adapted to have its ends ancho'red on a surf face, and strapsfitting on the ends of said har and adapted to be secured to a floor.

4. A wheel chock comprising a wheel gaging block having its lower face provided with a dove tait transverse groove, a bar' fitted in meet: gj theve with the e the l)2ll' prot'uding from the sides of the block, and st'aps fittecl on the ends said bar, said str aps having the ends thereof secured to a wheel sustaning surface.

5 5. A wheel check ee npri sing a block having a ti'e engaring end and a seenring` end hy which seid block may be anchored'on e floor, and detaehable means intermediate the encls of seid block and in a plane With ,the securing end of said block adapted to be z neherecl on the fi'oof to hold said block n the floor independent of the Seeuring eml of said lleek,

6. WVheel checking mea-m comprising opposed wheel engaging bloeks having lateral projeetiens, and means extending` over said bloek projeeton in the general direction of the bloeks and parallel thei-eto edapted 'for :mohoi-ing the projeetons of said bloeks.

In testinony Whereof I affix my signature.
